.SHORT TERM...
(Tonight and Monday)

Dryline storms rapidly developing this afternoon across the
eastern Permian Basin and western Concho Valley. TTU WRF and the
latest HRRR showed this nicely, and indicate that the storms
should continue to increase in coverage through the evening hours,
with perhaps another round developing after 06Z as the cold front
plows into the area. Storms should shift east out of the area
after sunrise Monday as drier air works it way in from the west.

.LONG TERM...
(Monday Night through Sunday)

Upper level shortwave trough exits to the east and leaves dry
conditions for Monday Night. However, could see a few storms
develop across the far southeast counties on Tuesday and Tuesday
Night as the low level moisture returns just ahead of anotherweak
shortwave. Better coverage of storms possible Wednesday and
Thursday as a cold front moves into the area. Upper level ridge
tries to build into the Southern Rockies for the weekend,
producing northwest flow across the Southern Plains. Combine this
with a dryline from the Panhandle to the Permian Basin and this
sets the stage for more convection possible for next Saturday and
Sunday.
